Chilly and wet (4)
I believe the answer is:
dank
'chilly and wet' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for dank that I've seen before include "(Of atmosphere) wet and unpleasant" , "Damp, cold, musty" , "Unpleasantly cool and humid" , "Unpleasantly wet and cold" , "Clammy, damp" .)
